In the following description similar characters of referenceindicatelike parts in the several 5 1flgures of the drawings:

The typewriting machine which is shown in the drawings is typical of onesuitable for use in connection with my invention, and as there shown thesame comprises a main frame ID, a 5' carriage II which is movablehorizontally and transversely on the main frame, a cylindrical platen I!which is mounted horizontally and transversely on the front part of thecarriage, front and rear lower guide rollers l3 and II v arrangedadjacent to the front and rear parts of the platen adjacent to theunderside of the same for holding the record sheets or leaves l5 and themanifolding carbon sheets I6 which are intercalated therewith againstthe platen, and

front and rear supporting bars l1, l8 forming 5 part of the carriage.

Means are provided for retracting the guide rollers l3, l4 fromtheplaten l2 so as to permit of the ready introduction of the sheets orleaves of paper which are adapted to receive the rec- 10 0rd and carbonmanifold sheets which are interleaved between the same, and thenreleasing these guide rollers l3, M in order to permit the same to pressthe intercalated record and carbon sheets against the platen so thatupon' rotating the latter the several record and carbon sheets will bemoved forwardly or backwardly and present the desired surface of thesesheets to the printing line, which in this particular typewriter islocated on the front side of the platen.

Inasmuch as the means whereby the carriage is moved step by step acrossthe machine, the platen is turned either forwardly or backwardly and theguide rollers l3, H are moved either toward or from the lower part ofthe platen, are all of well-known and standard construction, a detaileddescription of the same is unnecessary.

The manifolding device containing my improvements is constructed asfollows:

In its general organization this manifolding 3 device comprises aframewhich-in the preferred construction is detachably mounted on the upperpart of the carriage andabove the platen, andclamping means mounted onthis frame and adapted to either grip the opposite side edges of thecarbon sheets and permit the record sheets to be moved lengthwise of thecarbons independently of the latter, or to release the carbons andpermit the same to move lengthwise with the record sheets. For thepurpose of utilizing the 40 present manifolding device the carbonmanifolding sheets are wider than the record sheets and, when assemblingthe same, these carbon sheets are intercalated with the record sheets sothat the opposite longitudinal side edge portions or edges of the carbonsheets project laterally beyond the longitudinal side edge portionsoredges of the record sheets, as shown in Figs. 1, 4, 6 and 'l. s

. Although the drawings and the following description show and refermore particularly to the use of a plurality of carbon sheets which arealternated with a plurality of record sheets in the assembly of .asection or set of such sheets,

it is to be understood that this invention is equal ly useful whenemploying but a single carbon sheet betweentwo record sheets, theforemost of which receives the main or ribbon impression of the typewhile the second receives the record through the medium of the carbon.Itis therefore to be understood that this manifolding device is equallyuseful when employing a single carbon sheet or a plurality of carbonsheets, and in the following description and claims the term carbonsheets is to be understood as including either a single sheet ofmanifolding carbon or a plurality of such sheets.

This manifolding device is more particularly intended for use incontinuous billing in which the record is simultaneously made on aplurality of sheets or leaves constituting a set, and each set forms asection of a plurality of webs or continuous sheets or strips which havebeen previously folded in zig-zag fashion and stacked in a pile in rearof the typewriting machine, as shown in Fig. 9, preparatory to being fedsuccessively through the typewriting machine for producing records ofvarious kinds on the several sets of record sheets. As the record oneach set of typewritten sheets is completed the respective set of recordsheets is torn or severed from the sheets in the next following set orsection of the plurality of webs preparatory to producing another recordon the last-mentioned set of record sheets. The line of division betweenone set or section of record sheets and the next following set orsection of such sheets is preferably located in the folds l9 between theadjacent sections of the several webs and along these folds each of thewebs is provided with a transverse line of perforations 20, as shown inFigs. 6 and 7, so as facilitate tearing one set or section of sheets ofthe web from another set or section thereof. If desired, however, thesevering of one set or section of the sheets in the continuous web fromthe sheets of another section thereof may be effected by any suitableform of cutting device which may be operated either manually ormechanically.

In its preferred form the frame of this manifolding device comprises twovertical end plates or heads 2|, 22 arranged lengthwise over the platenand the carriage bars l1, l8 adjacent to opposite ends thereof, a lowerhorizontal transverse bar or rod 23 arranged above the platen andconnecting the lower parts of said end plates, and an upper horizontaltransverse bar or rod 24 arranged above the lower bar 23 and-connectingthe upper front parts of the end plates.

On its underside each of the end plates is provided about midway of itslength with a downwardly facing V-shaped seat 25 which engages with thecorrespondingly shaped seat on the upper side of the carriage bar [1, asshown in Figs. 2 and 5. At its rear end each of the end plates 2|, 22 isprovided with a notch 26 forming in ef-' feet a forkwhich extendsrearwardly and receives the rear cross bar [8 of the carriage, as shownin Figs. 2, 3 and 5. The manifolding frame may be held in engagementwith the carriage by any suitable means, but this is preferablyaccomplished by means of catches 21 movably mounted on the outer side ofeach of the manifold end plates about midway of the length thereof, andeach provided at its lower end with a hook 28 engaging with theunderside of the adjacent carriage bar I! and provided between its endswith a longitudinal slot 29 which receives a clamping screw 30 on theadacent part of the respective end plate, a finger piece 3! arranged atthe upper end of each catch 21 for convenience in manipulating the same,and a screw nut 32 working on the respective clamping screw 30 andengaging with the outer side of the catch 21, as shown in Figs. 1, 3, 4and 5.

Adjacent to opposite ends of the manifolding frame the same is providedwith two pairs of gripping devices whereby the carbon sheets may begripped and held against longitudinal movement but permit the recordsheets to be moved 5 lengthwise independently of the carbon sheets, andthese gripping devices may also release the carbon sheets so as topermit the same to move lengthwise through the machine with the recordsheets. 10

Each of these gripping devices comprises a rear gripping jaw 33 which isinclined rearwardly and arranged in rear of the corresponding edgeportions of the record sheets and the manifolding sheets at one of thecorresponding longitudinal l5 edges thereof, and a front jaw 34 which isarranged in front of the companion rear jaw and in front of thecorresponding longitudinal edge portion of the manifolding sheets, butbeyond the adjacent longitudinal edges of the record sheets. It followsfrom this construction that when the two gripping jaws of each pair arepressed together, only those edge portions of the carbon sheets whichproject beyond the record sheets will be gripped and thereby hold thecarbon sheets against motion but permit the I. record sheets to be movedlengthwise independently of the carbon sheets, while upon releasing thejaws from the carbon sheets the latter are free-to move lengthwise withthe record sheets. In the preferred construction each of the reargripping jaws is pivotally mounted to swing in a vertical planelengthwise of the machine, for

. which purpose this jaw is provided at its vertical opposite edges withrearwardly projecting flanges 35 which are pivoted at their upper endson the upper cross bar 34 of the manifold frame. In order to permit eachof these rear gripping jaws to swing the requisite extent withoutinterference with the lower manifold frame bar 23 the flanges 40 35 areprovided in their lower parts with rearwardly opening notches 36 whichare opposite the bar 23 and therefore clear the latter upon swinging therespective rear gripping jaw 33 forwardly and backwardly, as best shownin Fig. 2. Each of the front gripping jaws 34 is stationary relative tothe companion rear gripping jaw but is pivotally mounted so that thesame can swivel or turn in a vertical plane lengthwise of the machine asufficient extent to permit I this front jaw to freely adapt itself tothe front side or surface of the side edge portions of the respectivecarbon sheets. For this purpose each of the front gripping jaws ispivotally connected by means of a horizontal transverse pin 31 with arearwardly projecting finger 38 which is formed on the front end of anarm 39 which is secured at its rear end to the adjacent end plate of themanifold frame.

The movement of the rear jaw toward and 6 from the companion front jawof each pair for either gripping or releasing the grip on the carbonsheets may be effected in various ways but the means which are shown forthis purpose in the drawings are so organized that a yielding pressureis exerted against each of the rear gripping jaws and thus enable eachpair of gripping jaws to automatically adapt themselves to variations inthe thickness of the carbon sheets and also to any variation in thenumber of carbon sheets which may be employed.

As best shown in Figs. 2, 3 and 4 a cushion spring 40 preferably of leafform is arranged in rear of each of the rear gripping jaws and securedthereto at its upper end while its lower end is free, and in rear of thefree part of each of these springs is arranged a rotary cam or eccentric4I, which latter upon being rotated so as to engage its salient partwith the cushion spring 40 will cause the respective rear gripping jawto be moved toward the companion front gripping jaw for holding therespective ends of the carbon sheets against movement, while uponturning this cam or eccentric so as-to present its receding part to thecushion spring the pressure on the respective rear gripping jaw will bereleased and thereby permit this jaw to drop by gravity away from therear side of the carbon sheets and permit the latter to be moved in themachine.

The eccentrics or cams associated with the two pairs of gripping jaws onopposite sides of the manifold frame are turned in unison into and outof their operative position by means of a horizontal transverse shaft 42which is journaled at its opposite ends in the end plates of themanifold frame, and is provided at one end with a hand lever-or arm 43for operating the shaft.

The throw of the cams 4| into and out of their operative position ispreferably limited by means of front and rear stops 44, 45 arranged onone of the end plates of the manifold frame adjacent to the shiftinglever or arm 43 so that when the cams 4| are moved rearwardly into theirinoperative position the shifting lever 43 will engage the rear stop 45and when the cams move their salient parts against the cushioning spring40 said hand lever d3 engages with the front stop 44 and limits themovement of the cams in this direction.

The arrest in the operative movement of the cams preferably occurs whenthe salient faces of the same are on a dead center or slightly beyondsuch center so that the pressure of the cushioning springs 58 willoperate to hold the shifting cams in their operative position withoutrequiring any other mechanism for this purpose and still permit thesecams to be easily released from the cushioning springs and moved intotheir rearward inoperative position when required.

In the use of this manifolding device one or more carbon sheets areassembled with the two or more leaves or sheets in the first section orset of the continuous webs, so that the opposite ends of the respectivecarbon sheet or sheets project laterally with their longitudinal edgesbeyond the corresponding longitudinal edges of the record sheets; Thefront ends of the foremost set of assembled record and carbon sheets arethen passed downwardly between the rear side of the platen and the rearg ide roller it, thence upwardly between the underside of the platen andthe front lower guide roll it and then the advancing edges of theserecord and carbon sheets are moved at their opposite longitudinal edgeportions over the rear jaws of the two pairs in such position that therecord sheets clear the front gripping jaws but the longitudinalmarginal parts of the carbon sheets are brought underneath the frontjaws of the two pairs of gripping devices, as shown in Fig. l.

The record sheets and carbon sheets are now in condition to permit ofproducing a multiple record consisting of a ribbon impression or writingon the foremost record sheet and carbon impressions of the type on theremaining inner sheet or sheets through the medium of the intercalatedcarbon sheets in a well-known manner.

The length of the carbon sheets is preferably so determined that thesame do not exceed the length of the sheets or leaves in each set orsec-- tion of the webs, and these are so assembled that the carbonsheets are within the boundaries of the respective record sheets, asshown in Fig. 6. 5 After the desired record has been typewritten on therecord sheets by the manipulation of the type bars and the means forshifting the carriage transversely and also feeding the paper lengthwiseas the writing progresses, the operator advances both the carbon andrecord sheets lengthwise a sufficient extentto bring the lower or rearends of the carbon sheets underneath the front jaws of the two pairs, asshown inFig. 6. The

rear jaws of the two pairs are now pressed forwardly by rotating thecams 4! in the proper direction through the medium of-the hand lever 43,whereby the marginal parts of the carbon sheets are gripped adjacent totheir lower or rear ends between the two pairs of gripping jaws, asshown in Figs. 2 and 4, and these carbon sheets. are held againstlongitudinal movement. The operator now retracts the lower guide rollersl3 and I4 so as to release the webs of record sheets and permit theoperator, by grasping the upper ends of the .foremostset of leaves orsheets of these webs, to pull the same forwardly independently of thecarbon sheets a suflicient extent to bring the line of division betweenthe foremost set of sheets and the next following set of sheets abovethe upper edge of the set of carbon manifolding sheets. When this hasbeen done the operator can separate the set of completed rec- 0rd sheetshaving the desired writing thereon by severing this foremost set ofrecord sheets from 3 the next following set of record sheets, which in.the present instance is best accomplished by tearing these two sets ofsheets apart along the lines of perforations located at the creases orfolds between the rear ends of the sheets of the fore most set and thefront ends of the next following set of record sheets.

During this operation the set of sheets of the webs which now becomesthe foremost set of the webs has its lowermost part arranged adjacent tothe printing line of the platen, and it is therefore necessary to backup the webs in order to bring the top of the sheets of the foremost setof the web to the printing line for the purpose of starting the writingof another record. Before, however, backing up the sheets of the rec-0rd webs the cams 4| are turned so as to release the grip of the twopairs of jaws from opposite ends of the carbon manifolding sheets sothat when therecord sheets are moved backwardly for bringing the top ofthe foremost set of sheets to the printing line the carbon sheets willbe also moved backwardly with these record sheets and in the properposition to produce multiple copies of the record as the writing of thesame progresses. This operation of gripping the lower end of the set ofcarbon sheets at the completion of each writing operation on a set ofrecord sheets, then drawing the webs forwardly so that the foremost setof sheets of the web are clear of the carbon sheets and bringing thenext following set of sheets into an intercalated position relative tothe carbons, then tearing off the foremost set of finishedJrecord sheetsfrom the next following set which is intercalated with the carbonsheets, and then releasing the carbons and backing the I same up withthe associated record sheets forbeginning a new typewriting operation-isrepeated in like manner for each manifolding operation.

From this it will be seen that the carbon sheets 7 need only be insertedmanually once between the foremost set of sheets or sections of thecontinuous webs, and that thereafter the same carbon sheets may be usedrepeatedly in association with the sheets or leaves of successive setsor sections of the webs without necessitating assembling and'disassembling the carbon sheets and succeeding record sheets, as hasbeen the usual custom heretofore, thereby materially expediting theproduction of multiple records of this character and reducing the timerequired for this purpose as well as effecting a substantial saving incost for doing the same.

It has been found in actual practice that when drawing a plurality ofrecord sheets for wardly relative to one or more carbon sheets while thelatter are held stationary in order to transfer the carbon sheets fromthe foremost section or set of sheets of the webs to the next followingset or section of sheets that the shoulders which exist at the foldsbetween adjacent sections are liable to catch the lower transverse edgeor edges of the carbon sheets and either crumple or tear the same so asto interfere with the manifolding operation or impair the quality of themanifold work which results from either tearing the carbons or wrinklingthe same.

This tendency of the record sheets to catch at the turns between thesame on the lower edge of the carbon sheets is further increased whenthe line of division between adjacent sets of sheets at the turnsthereof is defined by the perforations 20 which are usually employed tofacilitate tearing or, severing of one set of sheets i from another inthe webs.

The catching of the record sheets against the lower edges of the carbonsheets by engagement of the shoulders or perforations at the junctionbetween adjacent sets of record sheets in the web is due to the factthat these shoulders and perforations are arranged along transverselines on the webs and engage simultaneously with the lower edges of theseveral carbon sheets if these lower or rear edges of the carbon sheetsare also arranged on a transverse line which is arranged at right anglesto the longitudinal movement of the record sheets. If such asimultaneous engagement of the shoulders or perforations at the divisionline between adjacent record sheets'with the lower edges of the severalcarbon sheets is permitted to occur a substantial upward pull wouldoccur on the carbon sheets along substantially the entire lower edgewhich the carbon sheets are not capable of resisting due to the delicatecharacter of the tissue from which the same are made. Such displacementor rupturing of the carbon sheets is objectionable and seriouslyinterferes with the proper operation of this manifolding device.

In order to avoid this result the lower transverse edge of each carbonsheet is arranged obliquely or at an angle to the longitudinal line ofmovement of the record sheets, as shown at 46 in Figs. 6, 7 and 8. As aresult of the angularity of the lower edge of each of these carbonsheets the transverse shoulder which is formed by the fold, crease orline of perforations on the record vebs between adjacent sections orleaves at right angles to the longitudinal line of movement will onlyengage with the oblique lower edge or edges of the carbon sheets along acomparatively small area of contact at any one time, as indicated at 4'in Fig. 7. This area of contact between the shoulders of the recordwebs'along the lines between adjacent sets of sheets and the lower edgesof the carbon sheets will therefore begin at the lowermost part of theoblique lower .edge of the carbon sheets adjacent to one pair ofclamping jaws and then progress successively upwardly and transverselyacross the inclined lower edges of the several carbon sheets toward theother pair of carbon sheet holding'laws, and then slide off in betweenthe broad faces of the several carbon sheets.

It follows from this that the lower edges of the carbon sheets are at notime engaged over any considerable area by shoulders on the record websand no tendency therefore exists to produce any substantial pull overany considerable area of the lower edge of the carbon sheets, wherebythe latter are not drawn upwardly from their lower edges and neitherdistorted or displaced to such an extent that they are torn or wrinkled,whereby the objectionable results above-mentioned are avoided.

Although it is only necessary to arrange the lower edges of the carbonsheets obliquely for the purpose of accomplishing the above results, itis also preferable to construct the upper edge 41 of each carbonmanifolding sheet of oblique or angular form relative to thelongitudinal line of movement of the record sheets, as shown in Figs. 6and '7, in order that the same carbon may be interposed between therecord sheets with either of its transverse edges arranged at the rearend thereof and thus avoid any particular care on the part of theoperator when assembling such carbon sheets with the record webs.

If desired, however, only the lower edge of the carbon sheet may be ofoblique form and the upper edge thereof may be arranged at right anglesto the longitudinal line of movement of the record sheet through themachine, as shown at 48 in Fig. 8.

In both cases, however, the longitudinal edges 49 of the carbonmanifolding sheets are parallel with the longitudinal line of movementof the record sheets inasmuch as this form of sheet is more practicalfrom a manufacturing standpoint, and it is also desirable for the samereason to make both the upper and lower edges of the carbon sheets ofoblique form and parallel with each other so that the same in effecthave the shape of a parallelogram.

In order to permit of thus holding the carbon sheets securely at theirlower edges while arranged obliquely relative to the length of themachine and the line of movement of the record sheets the rear jaws ofboth pairs of grippers are preferably of the same length but thecompanion front jaw of one pair, for example the right hand jaw 34 asshown in Figs. 1, 6 and '7, is arranged somewhat lower than the frontjaw associated with the pair of grippers at the left hand side of themachine, which relative longitudinal displacement of these two frontjaws corresponds to the angularity of the lower edge of the carbonsheets and enables both of these front jaws to grip the carbon sheets attheir lower edges adjacent to the side edges thereof in cooperation withthe rear jaws. By this means the several carbon sheets are held properlyin position against liability of being wrinkled by the upward movementof the record webs when substituting an unwritten set of sheets for thepreviously completed set of sheets, while at the same time leaving thoseparts of the carbon sheets above the clamping jaws free to be smoothedout by the upward sweep of the record sheets past thesame and thusmaintaining the carbon sheets always in a smooth and unwrinkledcondition for producing good carbon reproductions of the typewrittenmatter.

It has been found by experience that no difiiculty is experienced infeeding those upper edge portions of the carbons underneath thatparticular front gripping jaw which is lowermost, but in themanipulation of the carbons the upper parts of the carbons adjacent tothe opposite longitudinal side thereof are apt to be turned back orcurled over by engagement with the low er end of the elevated or lefthand front gripping jaw due to an interference between this jaw and thecarbon sheets. In order a; avoid this the front upper or advancedgripping jaw, which in this case is at the left hand side of themachine, is provided at its lower edge with an inclined guide 50 whichprojects forwardly a sufficient extent so that when the operator movesthe left hand edge of the carbons upwardly the same will be directed bythe guide 50 underneath the left hand jaw 34 without any liability ofinterference between these parts or any displacement of the carbonsheets.

. In the standard Royaltypewriter the record sheet, when using themachine for ordinary writing, is held down upon the upper part of theplaten by means of guide rollers which are mounted on a shaft 52 havingits opposite, ends movably connected by means of verticallyswinging'arms 53 with the rear part of the carriage. Inasmuch as therollers 5| would interfere with the application of the presentmanifolding device to the Royal typewriter these rollers are movedupwardly and rearwardly away from the platen in the position shown inFigs. 1, 2 and 3, and utilized as part of the guide means for directingthe webs of record sheets from the supply stack to the platen.

If desired the faces of the gripping jaws may be serrated, scored orgrooved, as shown at 54 in Fig. 5, for the purpose of increasing thehold of the same on the carbon sheets. v

As a whole this manifolding device is very simple in construction, thesame has comparatively few parts, all of which can be readily manip- Iulated without liability of getting out of order, and the same can bereadily applied to and removed from typewriters of standardconstruction, and thus permits the same typewriter to be convenientlyused either for ordinary typewriting or for continuous billing.
